How this service works
Batch PQS scoring. Score up to 10 prompts in a single call.
Output
Returns a quality score for each submitted prompt, indicating how well-formed, clear, and effective each prompt is likely to be for its intended vertical.
Example use cases
Example prompt
“Can you score the quality of these three prompts for me and tell me which is best — I want to use the 'software' vertical: 'Write a Python function to sort a list', 'Sort a list in Python', and 'Please write an efficient, well-commented Python function that sorts a list of integers in ascending order using a custom comparator'?”
Technical details
Endpoint
GEThttps://api.relai.fi/relay/1779373065272/api/score/batchWhen to prefer
Use this endpoint when you need to evaluate or compare the quality of multiple prompts (up to 10) in one call, especially when working with domain-specific verticals like software, content, business, or research. Prefer this over single-prompt scoring when batch efficiency matters.
Side effects
- More than 10 prompts submitted — returns validation error
- Empty prompt string — minLength:1 violation
